Title: Photographic camera having a flash range display
Inventor: BELITZ FRITZ DR
IPC: G03B15/05
Filed: 1981-10-09
Abstract: A photographic camera is described, which has an exposure metering device and a computer flash gun controlled by the photocell of the exposure metering device, and which has a display device for the distance range illuminated by the flash. On the camera, the aperture setting device and the film speed setting device are disposed adjacent to one another. Both the aperture setting device and also the film speed setting device are coupled with means by which these parameters are fed into the measurement current circuit of the flash gun. A distance scale which is graduated logarithmically to the base (2) is provided on the camera in fixed correlation with the film speed setting device or with the aperture setting device, on which distance scale a doubling of the distance corresponds to the subdivision of two aperture steps on the aperture setting device or of 6 DIN on the film speed setting device. A range marking is fitted on the aperture setting device or on the film speed setting device, opposite the distance scale disposed on the respective other setting device, the length of which range marking indicates, at all settings, a distance range between a maximum distance and for example 1/N of this maximum distance. It is possible to provide, for example, grey wedges as means for inputting the aperture and the film speed. However, these parameters may also be input via variable electrical components in the measurement current circuit of the flash gun.

Title: Circuit for evaluating track voltages in railway systems
Inventor: MEGE KARL-HEINZ ING GRAD
IPC: B61L1/18
Filed: 1981-11-11
Abstract: Frequency-modulated signals are used with a view to improved safeguarding of correct assignment of electrical signals for all-clear signalling and occupied signalling of a track circuit on the one hand and of an evaluation device on the other, specifically for each track circuit with a code which is typical for said circuit. A digital circuit with a period duration measuring device, in which the track voltage supplies the time base, serves to evaluate these frequency-modulated track voltages with a low modulation index. The pulses of a quartz generator (G) are counted by a multi-stage binary counter (BZ). The outputs of this binary counter (BZ) are connected to the inputs of a storage and converter circuit (SU). The latter is programmed in such a way that two address areas are specified while taking into account predetermined tolerances of the upper and lower frequency value of the track voltage, by means of which address areas a first or second identification is output only in the case of upper or lower counter results of the binary counter (BZ) lying in the tolerance range. The identifications are finally fed to a decoder element (DD) which only outputs an all-clear report for the respective track section in the case of frequency-modulated telegrams which are assigned to the respective track section. <IMAGE>

Title: Ball-striking implement, in particular tennis, soft tennis or squash racket, with variable centre of gravity
Inventor: PICHLER OSWALD
IPC: A63B49/04
Filed: 1982-03-03
Abstract: To vary the point of balance of a ball-striking implement, in particular a tennis or squash racket, a peripheral cord, strap (14) or the like is arranged inside the frame (12) of the ball-striking implement, which cord can be driven from the outside and to which a weight (10) is attached.

Title: Arrangement for controlling control amplifiers in sound-mixing desks
Inventor: STOLDT ULRICH DIPL ING
IPC: H04H60/04
Filed: 1982-03-15
Abstract: The arrangement for controlling control amplifiers in sound-mixing desks explained in the text which follows relates to sound processing systems which have a large number of input channels which in some cases must be influenced simultaneously or successively in order to obtain a mixed signal which is sound-aesthetically correct. The control amplifier is controlled by level controls. Since 30 and more input channels are no rarity, the mechanical width of all the level controls to be manually adjusted exceeds the dimensions which are within the handling range of one person or the legally permissible width in transmission paths. It is never necessary to adjust all the level controls at the same time by different amounts; it is therefore possible to use a lesser number of level controls as input channels and to switch these in each case to the required input channels if the level setting (level control value) is stored. The storage is carried out in the control amplifier which exists for the respective input channel. The drawing below shows a level control (1) with a switch-over device (2) and five control amplifiers (3, 4, 5, 6, 7) for the sound signals. <IMAGE>

IPC: F03B13/18
Filed: 1983-06-09
Abstract: In a float g, which bobs on the waves and is held against drifting and twisting by means of retaining cables i and i1 from fixed bollards k2 to k4, there are accommodated a plurality of units for generating current from which shaft butts (stub shafts) b2 of the drive sprockets b1 project freely and effectively sealed into the water, over the cable drum and e of which wire ropes f are wound which are suspended by one end in eyes 7 fastened under water and whose free ends are hung with drive weights h1, thus imparting to the float g a further variable hold in the vertical direction. When the float rises, the weights h1 are raised, and not until being lowered do said weights turn the generators d via the gears in conjunction with the clutches cl which are then engaged. Using articulated systems such as balance beams yl, z and zl, a plurality of wire ropes f are guided onto a drive shaft b with balanced tensile loading, and so the hoisting (lifting) power (capacity) of the individual generating units, and thus that of the float g are increased. The generating units are accommodated in the watertight housings l inside the float. <IMAGE>
